The ability to disagree does not produce a flaw with a definition. All meaningful assertions should have an opposing one. Subjectivity becomes a problem in debate when it leads to SUBJECTIVE definitions. As in: "The car is big". Here one might ask, what does big mean? As with morality, one one then establish a presiding argument ("big" means bigger than 10 feet long for example), and if you agree with this objective definition, one can continue the argument. It seems like you need to get your terminologies sorted through.
The goal of moral debates isn't necessarily to achieve some "best" morality, in which the "best" leaves behind great ambiguity. It is merely an examination of a situation following different axioms of logic.
How do I need to get my terminologies sorted through?
Subjective: taking place within the mind and modified by individual bias.
I never said the definition, itself was flawed. I said the argument that follows it must surely be flawed.
Example:
* For this example, my definition of murder is: Intentionally exterminating the life of another human without their consent.
A drug-lord murders someone who steals from him. Billy is outraged, and demands his head. While, Jimmy sees nothing wrong with it, as he finds it morally acceptable. They argue because of their definition of moral, and immoral. And they are as follows:
Billy defines immoral as, "Murdering anyone, any time, any place."
Jimmy defines moral as, "Getting revenge on any person who has done you wrong, by any means possible."
The two are definitions are subjective, not flawed, like I already asserted. Now, to debate one has to use logic. Surely, you can agree it's not logical to argue "apples and oranges."
To sum up, my argument is this:
- The definition of moral/immoral is subjective.
- Your outlook on morality is hard-wired in your brain. No debate will ever make you disagree.
- Therefore, debates are useless, since both sides will
never agree.
Yes, but the arguments need not begin there, even if they end there. Once again, I would argue that the definition of the argument isn't the subjective part, it's the eventual arrival at the fundamental disagreement.
Would the fundamental disagreement not be at the definition? Surely you can agree that if they both accepted one definition as moral, there would be no need for an argument.
